Question

How are u supposed to tell how many neutrons and electrons an element has?? Pls help if u know the answer.

Answer 1

Step-by-step explanation:

The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
